Chromostereopsis #2
Advancing color and receding color

For many people, the effect is larger when they see the figures with a distance of more than 1 meter. In my knowledge, more than half observers see red in front of blue when the background is black, while about 20% see blue in front of red.

"Chromostereoscopic windows"

More than hald of observers see black random dots in front of blue ones. But there are a few observers who see the blue in front of the black.

"White grid on the black disks"

The white grid appears to be in front of the black disks. The illusory black dots are the scintillating grid illusion or the Bergen illusion. This illusion disappears when we keep blinking! In addition, the white grid sometimes appears to be yellowish.

Warning: Do not keep blinking too frequently. Blink vibrates the retinas in the eye balls, which might possibly cause serious disorders, e.g. retinal detachment or hemorrhage of the fundus for those who have too strong nearsightedness, high blood pressure or diabetes.


"Red target"

The red circle appears to be in front of the blue ring for more than half people.

"Apparatus to talk to aliens"

For more than half people, the circumference of each ring appears to be in front. In addition, the 'mist' in the ring center appears to move when observers move their eyes (saccade).
